No speakers come with this unit . Most any speakers will work , but try to find the most efficient for your money that run on less watts . I have a Klipsch center channel , Pioneer mains , and KLH surrounds with a Velodyne powered sub . Stay away from Bose , they are a joke .
It will not wake up on it own, but you can turn it on with the free Yamaha remote app on your smart phone or tablet via wifi. If you have it on and air play to it it will automatically switch to your music. Sorry to say it does not airplay video like the Apple TV. I have a iPhone 5 so I don't see you having a problem with the iPhone 5s.
According to the manual on pg 61 and pg62 you can play the same input source, analog or digital in zone A and Zone B. It does not specifically say analog only as it has in the past. It does make it sound like it has to be the same input source in both areas.
